Abstract
A combined dose rate meter and charger unit therefor which does not require he use of batteries but on the other hand produces a charging potential by means of a piezoelectric cylinder which is struck by a manually triggered hammer mechanism. A tubular type electrometer is mounted in a portable housing which additionally includes a Geiger-Muller (GM) counter tube and electronic circuitry coupled to the electrometer for providing multi-mode operation. In one mode of operation, an RC circuit of predetermined time constant is connected to a storage capacitor which serves as a timed power source for the GM tube, providing a measurement in terms of dose rate which is indicated by the electrometer. In another mode, the electrometer indicates individual counts.
